I understand that AI can very commonly convince us of things that it doesn't find right away as "novel". I'm well aware of amateur mathematicians being convinced that they invented something amazing only to find it was known for hundreds of years in professional circles! I have indeed searched of similar concepts myself but I could not find anything close to the idea. And the reason for the entire engine rework for a "2D RTS" is that such engines are insufficient for my concept which "technically" is computed in 3D albeit using ring buffers and complex math optics. Basically every RTS engine out there functions in the same way, a unified map "state" that everything interacts with, what players see is what players interact with. It's all happening live on the same map (with some fog-of-war to hide stuff). My twist comes from replacing the fog of war with something far more complicated.
I'll probably share the concept in another topic since this topic was more about the AI sentiment regardingg AI coding (not related to AI art/music/sound assets). As for whether my game concept is "fun" is another question as well, but I am sure it will be unique.
